Evaluation of results and costs of high precision radiotherapy (VMAT) compared with conventional radiotherapy (3D) in the treatment of cancer patients with spinal cord compression of metastatic origin

BackgroundThe aim of this study was to evaluate the results and economic costs of using volumetric modulated arc therapy (VMAT) (5 fr × 5 Gy), compared with other conventional 3D radiotherapy schemes such as "5 × 4 Gy" and "10 × 3 Gy". Materials and methodsThe data about the dire...

Description
Summary:BackgroundThe aim of this study was to evaluate the results and economic costs of using volumetric modulated arc therapy (VMAT) (5 fr × 5 Gy), compared with other conventional 3D radiotherapy schemes such as "5 × 4 Gy" and "10 × 3 Gy". Materials and methodsThe data about the direct costs for the public health system was obtained from the Economic Information "Management per Patient" System available at the Integrated Health Organization Ezkerraldea Enkarterri Cruces. It is a model of real costs per patient which uses a bottom-up methodology which connects all sources of information generated in clinical practice, integrating healthcare information with economic information. This system presents the real cost per individualized patient, and shows the traceability of all clinical care. The costs of "typical patients" requiring hospital admission were identified for each of the three radiotherapy schemes based on the clinical activity and the material and human resources that were used. ResultsThe 5 × 5 Gy scheme has a cost of EUR 4,801.48, which is 1.64% higher (EUR 77) than the "5 × 4 Gy" scheme (EUR 4,724.05). The "10 × 3 Gy" scheme has a cost of EUR 8,394.61, which is 74.8% higher (EUR 3,593) than the "5 × 5 Gy" scheme. The main cost factor in the "10 × 3 Gy" scheme is hospitalization, since patients are at hospital for 2 weeks compared with 1 week in the "5 × 5 Gy" scheme. ConclusionsThe cost per patient of the VMAT "5 × 5 Gy" radiotherapy scheme is notably lower than that of the "10 × 3 Gy" scheme (conventional 3D radiotherapy), with the advantage of being administered in half the time. In relation to the scheme with 5 Gy × 4 sessions, the cost is similar to that of the "5 × 5 Gy" scheme.
